Abstract

A refrigerator is proposed, when a drawer of the refrigerator is completely opened, the center of an opening-detection magnet provided at the lower surface of the drawer may be disposed by exceeding the center of the sensor of a reed switch, in a moving direction of the drawer, installed at the bottom surface of the inside of the cabinet. Accordingly, the sensor may accurately detect the magnet, and even if external impact is applied to the drawer in the completely opened state of the drawer, the malfunction of the drawer which is closed unintentionally may be prevented.
